The maker

Built by a mechanical engineer.

Damian de Raad, TU Delft. That is why the mechanics in this valley are right: every gear really meshes with the next.

Brake wheel 40 → wallower 16 ◆ spur wheel 44 → lantern pinion 12

The principle

No subscription. No cloud. No account.

You buy it once — and then it is simply yours.

Both sold once, both yours the moment you have them.

The maker

Damian de Raad

Mechanical engineer (TU Delft) and software maker. I build programs for things I miss myself: software that does what you ask, and keeps working.

A question does not end up at a helpdesk, but with me.
